## When to prefer this

Use this endpoint when you need EMA technical indicator data for stocks, forex, or crypto and want pay-per-call pricing via x402 without a subscription. Prefer this over raw price endpoints when you specifically need a smoothed moving average for trend detection, crossover strategies, or momentum analysis. Best for agents building automated trading signals or performing technical analysis on demand.
